MACHINE FOR CALENDERING PAPER OR OTHER MATERIAL.

SPECIFICATION forming part of Letters Patent No. 555,385, dated February 25, 1896.

Application filed June l2, 1893.

To all whom it may concern..-

Beit known that I, HUGH LrN'roN, a citizen of the United States, residing at PaWtucket,in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Machines for Calendering Paper or other Material; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to Which it appertains to make and use the same.

The object of my invention is to provide a calendering-machine, and I accomplish this by the mechanism illustrated in the accompanying drauings, in Which- Figure l is a side elevation of amachine embodying my invention; Fig. 2, a vertical Cross-section on line fr: .11, Fig. 3; and Fig. 3, a front elevation.

Similar letters referto si milar parts throughout.

In Fig. l, A designates a suitable frame, secured to the floor by bolts a a. B designates a metal cylindrical roll, mounted in journal-boxes b l), Constructed in the side of the frame and terminating in a shaft b', upon which is mounted the tight pulley 112, said shaft revolving in the j ournal-box in the post Us, secured in any proper manner to the floor. This roll is a friction-roll, imparting its motion to the cylindrical roll C, of metal, mounted in journal-boxes c c.

D and E designate two metal cylinders, preferably of equal face, mounted as follows: a and 0.2 designate similar' branching arms of the frame A, converging at the same angle to the face of the cylinder C. At d" d journalboXes are constructed on these arms, in Which revolve the respective shafts d and e of the cylinders D and E. rlhese j ournal-boxes are adjustable Within the longitudinal slots s 3 of said arms ci. a by means of the large screvvs F. This adjustment is employed to force the rolls against the calenderin g-roll at any pressure required.

By reference to -3 it will appear that.

my machine is preferably supplied with three tight pulleys marked, respectively, b2 d2 e2, constructed with diameters respectively proportioned to the speed required of the respective cylinders. The pulleys di and e2 are re- Serial No. 477,360. (No model.)

spectively mounted upon opposite sides of the frame on the extensions of the shafts d and e, respectively. By reference to Fig. 3 it Will also be seen that I preferably set these cylinders one in front of the other in such a manner that the cylinder farthest from the delivery-roll will have the greatest speed.

II designates a suitable framework attached to the main frame A and secured to the floor, being adapted to receive the roll of material and deliver the same to the calendering-cylinder, as follows: in a slotted recess 7L on the front of the frame rests the bar h, upon Which the material is rolled. From this bar, in the direction indicated bythe arrow-h ead, the end of the roll is carried over the loose roll g, revolving in an arm of the frame; thence to and under a brush-roll K, mounted and revolving in suitable bearings in the side of the frame; thence between the cylinder D and the calendering-roll C. Thence the material is carried, by the revolutions of the pressing-rolls D and E and calendering-roll C revolved in the direction indicated by the arrow-heads, Fig. 2, to the receiving-roll L, mounted upon an arm l of the frame n journal-boxes Z2, Fig. l, and adapted to be revolved in its bearings by the pulleys Z3 and l4 and take up the material as fast as delivered.

The pulley e? I have preferably made larger than the pulley d2 that the speed of the roll E may be slower than that of D.

The manner of using my machine is as described above, the material to be treated being mounted in a roll at 7L', passed over the pulley g, under the brush-roll K, between the pressing-rolls and the calendering-roll, and thence to the receiving-roll L.

That I claim as new, and desire to secure by Letters Patent, is-- l. In a calendering-machine, a frame having slotted arms, a calendering-cylinder mounted in the frame, a j ournal-box in each slotted arm, a plurality of calender-rolls mounted in the journal-boxes, an adjustingscrew' threaded into each arm and bearing kagainst its respective journ al-box, and a friction-roll mounted in the frame and bearing against the calendering-cylinder, substantially as set forth.

2.' In a calendering-machine, the combina- IOO tion of tWo or more rolls, D, E, provided With all substantially as and for the purpose set Io pulleys, d2, e2, mounted and revolving in adforth.

justa-ble journal-boxes, f, f', a calendering- In testimony whereof I have hereunto set cylinder, C, mounted beneath said rolls in a my Vhand in the presence of subscribing Witframe, A, the friction-roll, B, mounted in said Vnesses.
